Stainless Steel Density Density of Stainless Steel

Stainless Steel Density is very important when we calculate the weight of stainless steel. If you just probably calculated, according to the general steel density is 7.85g/cm³, to carry out the calculation, the difference will not be great ( Such as 316 material price is very expensive, a rough budget entry would be very big ).

The following is the comparison of several commonly used stainless steel density meter, for reference purposes only. If you are only estimates, according to common steel density 7.85 / cm³ calculation.

Stainless steel materials, we can use the data to calculate the weight of relative theory, the calculating formula is

Weight ( kg ) = thickness (mm ) * width * length ( m ) ( m ) * density values ( g / cm³ )

Stainless steel welded pipe conveying fluid density

According to the national standard of content, according to China daily accumulation, reckoning the stainless steel approximate density ( kg/dm³ ) respectively:

Material Grade	309S	310S	316	316L	347	405	410	420	409	430	434
Density kg/dm³	7.98	7.98	7.98	7.98	7.98	7.75	7.75	7.75	7.70	7.70	7.70

Theoretical weight calculating formula is Calculation of Theoretic Weight

Steel products theoretical weight of Theoretic Weight

Weight ( kg ) = thickness (mm ) * width * length ( m ) ( m ) * density value

Weight ( kg ) = Thickness ( mm ) = Width ( m ) = Length ( m ) * Density ( g / cm³ )
